TUBING BLEEDEB.

' Application filed June 12, 1925. Serial No. 88,788.

To all whom it may concern: 7

Be it known that I, ELMER D. SMYSER, a citizen of the United States,residing at Fellows, in the county of Kern and State of California, haveinvented certain new and useful Improvements in Tubing Bleeders, ofwhich the followin is a specification.

This invention re ates to certain new and useful improvements in tubingbleeders for oil wells and the like, and has particular reference toimprovements in tubing bleeders of the type set forth in my copending application, Serial No. 19,744, filed March 31, 1925.

The primary object of the invention is to provide an improved andsimplified form of tubing bleeder by means of which liquid may bedrained from well tubes with facility and ease prior to removal of thetubes from the well casing for repairs or the like.

A further object of the invention is to provide a tubing bleeder of theabove character which is extremely sim 1e and durable in construction aswell as e cient in operation so as to meet with all of the requirementsfor a successful commercial use.

A further object is to provide a tubing bleeder which is inexpensive tomanufacture and install and which may be placed into operation withoutthe requirement of special skill or tools.

lVith the above general objects in view, and others that will becomeapparent as the nature of the invention is better understood, the sameconsists in the novel form, combination and arrangement of partshereinafter more fully described, shown in the accompanying drawings andclaimed.

In the drawings, wherein like reference characters indicatecorresponding parts throughout the several views.

Figure 1 is a fragmentary elevational view, partly broken away, of awell tubing equipped with a bleeder constructed in accordance with thepresent invention, the tubing and bleeder being illustrated in operativeposition within a well casing shown in central longitudinal section,

Figure 2 is a transverse sectional view taken substantially upon line2-2 of Figure 1 Figure 3 is a view similar to Figure 2 takensubstantially upon line 3-3 of Figure 1, I

Figure 4 is a fragmentary longitudinal sectional View, partly inelevation, showing the well tubing and bleeder'with arts of the latterin section and in side e evation,

Figure 5 is an elevational view of the device shown in Figure 4 lookingto the left of the latter figure and illustrating other parts 1 noperative association with parts shown 1n Figure 4 and, Y.

Figure 6 is an enlarged fragmenta elevational view showing the bleederva ve or plug and its seat.

Referring more in detail to the drawings, 5 indicates the lower sectionof well or pumn tub ng which is arranged within the welIl casmg 6 in theusual way, the tubing 5 being of considerably lesser size than the pumpcasing 6 and disposed concentrically within the latter so as to leave acylindrical space between the tubing and the casing as clearly shown inFigures 2 and 3.

In accordance with the present invention the lower tubing section 5 isformed with an opening inthe side thereof, and the wall of this openingis thickened to provide an outwardly projecting annular rib or flange 7which acts as a reenforcement. This annular rib 7 is preferably producedby Securing a ring in the bleeder tube opening and permanently bywelding or the like as clearly shown in Figure 4, the ring beinginternally threaded for detachable reception of a re-' movable annularseat member 8 whose opening is closed by the head 9 of a bleeder valveor plug which also includes a rigid outwardly projecting stem 10preferably formed integral with the head 9. The head '9 of the bleederplug or valve is preferably secured in place to close the opening of theseat member 8 by soldering or the like as indicated at 11 so thatleaking is prevented under normal conditions, but whereby the bleederplug or valve may be forcibly detached or dislodged from the seat member8 when it is desired to drain the fluid from the pump tubing 5 above thebleeder valve opening. In other words, the solder at 11 constitutes afragile means for securing the bleeder plug or valve in the seat member8 so as to close the opening through the latter and prevent accidentaldislodgement of the bleeder plug or valve from its seating position.

As shown clearly in Figures 5 and 6, the

seat member 8 is provided with a plurality of inwardly projecting lugs12 for fac1l1 tatin threading of said seat member 8 into the t readed oening of the pump tubing 5 by the use 0 a suitable'tool or wrench. It isthus apparent that the seat member 8 and its plug or valve normallyconstitute a renewable unit which ma be readily threaded into theopening of t e pump tubing, and, after the plug or valve has beenunseated, another unit may be put in place by removing the original seatring 8.

The ump tubin 5 is formed with an external annular e argement 13 abovethe bleeder opening as shown clearly in Figure 4, and this enlargementis externally threaded. Adjustably threaded upon the enlargement 13 is asleeve 14 whose lower edge is engaged by an anti-friction roller 15journaled 1n the up er end of a sliding bar which is mounts in guideloops 1 at one side of the well tubing 5 for movement longitudinally ofthe latter. The lower end of the sliding bar 16 engages the outwardlyprojecting stem of the bleeder plug or valve, and it is thus ap arentthat when the sleeve 14 is rotated in t c direction for causing itsdownward movement relative to the tube 5, or when the tube 5 is rotatedfor causing downward movement of the sleeve 14 roviding the latter isheld from rotation, t e bar 16 will be forced downwardly so as to causedisplacement of the bleeder plug or valve from the seat member 8 so thatthe opening in the latter will be opened for allowing the fluid to passout of the pump tubing 5 into the portion of the well casing 6 dis osedtherebelow.

In the operation 0 the device the sleeve 14 is preferably held againstrotation while permitted to freely lower, while the pum tubin 5 isrotated. This operation 1s e fecte preferably by the means shown whichincludes a air of collars 18 and 19 respectively slidably dis osed u onthe pump tubing 5 above and slow t e bleeder plug as shown clearly inFigure 1, which collars 18 and 19 are. connected by a plurality ofspaced longitudinally extending resilient strips or leaf springs 20which are normally outwardly bowed or efi'ective, frictional engagementwith the inner surface of the well casing 6. The pum tubing 5 isprovided with an annular e argement or collar 21 directly below thebleeder plug or valve, and this collar or enlargement forms an externalsto which is engaged by the lower sleeve 19 w an the pump tubin islowered into the well casin so that the s eeve 19 will not enga the beeder plug or valve and dis lace t e same from its seat member 8.

e upper sleeve 18 is provided with a rigid depending arm 22, and thethreaded sleeve 14 is provided with an outwardly projecting lug 23 asclearly shown in Figures 1 and 5. The arm 22 is of such length as tonormally have its lower end spaced above the lug 23 as shown in Figurel, but when the tubing 5 is elevated until the threaded sleeve 14engages the sliding sleeve 18 as shown in Figure 5, the lug 23 will bedis osed to engage the arm 22. In other wor s, when the um tubing 5 isthus elevated, turning 0 said tubing will effect the movement of the In23 into engagement with the arm 22. pon further turnin .of the tube 5,the arm 22 will engage t e lug 23 for preventin turning of the threadedsleeve 14 so that t e latter will remain stationarywhile the tubingthreaded u wardly therethrough. When this takes ace there is a relativeslidi movement etween the tube 5 and the bar 16 so that the sleeve 14forces said bar 16 downwardly and effects displacement of the bleederplug or valve. As soon as the bleeder plug or valve is displaced, thefluid will pass outwardly through the o enin in the seat member 8 andthus be di'ained from the pump tubing. The sleeves 18 and 19 and s ringstrips 20 thus constitute a frame slidably mounted on the pump tube 5and adapted to frictionally engage the well casing 6 with suflicientfriction as to be restrained from rotation so that when the arm 22 isengaged with the lug 23 the sleeve 14 will be restrained from rotationupon rotation of the pum tubin 5, whereby the sleeve 14 is fed lbngitudmally of the pump tubing 5 for causing movement of the sliding rod 16whereby the latter unseats the bleeder valve.

From the foregoing description it is believed that the construction andoperation as well as the advantages of the present invention will bereadil understood and ap reciated by those skil ed in the art.

inor changes may be made without departin from the s irit and scope ofthe invention as claime What I claim as new is 1.
